Crossing Continents: Somalia

They went in - with US backing - to chase an Islamist movement from the capital, Mogadishu. But anger at the presence of Ethiopian troops has boosted support for radical Islamist groups and in recent weeks, violence has increased.

BBC Radio 4's Crossing Continents was broadcast on Thursday, 1 May 2008 at 1102 BST.
